Thank you for buying JRC JCY-1850 Simplified Voyage Data Recorder (S-VDR).
This equipment helps to detect the cause of marine accident to prevent the recurrence in the
future. The equipment records voyage data, as required by the International Standard, during
the navigation and the hull data of the vessel.
• To ensure your S-VDR provide optimum satisfaction and service, read this manual carefully
before attempting to operate the JCY-1850.
• We recommend you to carefully store the manual for future reference.
• If you have any problems using this product, this manual will surely help you.
In order to detect the cause of marine accident, the S-VDR records hull data and navigation
information.
If an accident has occurred, it is mandatory to preserve the record data immediately.
In case an accident has occurred, please preserve the record data according to the procedure
described in 1.4.4: “Actions to be taken at the time of an accident”
To ensure the proper operation, we recommend you to read the procedure carefully.
ATTENTION
S-VDR erases older data that has passed for more than 12 hours and
overwrites new one.
Therefore if you do not operate properly, the recorded data at the time of
accident is erased automatically after 12 hours.
